About I/Q Analyzer (IQA) Measurements
The I/Q Analyzer Mode makes general purpose frequency domain and time
domain measurements. The mode enables two types of I/Q measurements:
— frequency domain and
— time domain measurements
In order to ensure consistent results between frequency domain and time
domain, spectrum measurement and waveform measurement are based on the
same I/Q acquisition. The following acquisition parameters are automatically
calculated to satisfy these requirements:
1. RBW and IF BW specified in Spectrum measurement BW (BW 2
) menu.
2. Start time and Stop time specified in Waveform measurement Sweep
(Sweep 3
) menu and IF BW specified in Waveform measurement BW
(BW 2
) menu.
3. I/Q signal capture related parameters specified in the Measurement Setup
(Meas Setup 4
) menu.
Some measurement parameters are auto-coupled and are not user-settable.
